The centaurs of Greek mythology are creatures that are part human and part horse. They are usually portrayed with the torso and head of a human, and the body of a horse. Centaurs are the followers of the wine god Dionysus and are well known for drunkenness and carrying off helpless young maidens.
If both healthy parents carry the same altered recessive. gene, then each child they have has a 25% (1 in 4) risk of. inheriting the altered gene from both parents and therefore. being affected. For each child, regardless of their sex, the. risk is the same = 25%. Children of couples who are both carriers of the same. altered recessive gene have a 50% (1 in 2) chance of. inheriting one copy of the altered gene from one of their. parents. If this happens, they are healthy carriers. themselves.
Many autosomal recessive conditions occur this way. As mentioned above, a person who carries one copy of an autosomal recessive gene is usually not aware they carry the gene. They do not show any signs of the disease or condition.It is estimated that all people carry about five or more recessive genes that cause genetic diseases or conditions.utosomal recessive inheritance means that the gene in question is located on one of the autosomes. These are numbered pairs of chromosomes, 1 through 22. Autosomes do not affect an offspring's gender.
